On 22 May 2023, Atul Joshi, Chief Engineer of MP Transco (Madhya Pradesh Power Transmission Company) informed that the company has innovated for the first time in the state with a power transformer of 160 MVA capacity at 220 KV voltage level. It is energized remotely with the help of (Human Machine Interface) technology.

Key points

• This advanced technology has so far been successfully used in new132 kV voltage level substations and 132 kV lines at MP Transco, which have been remotely energized.
• This is the first time a hyper-sensitive device like 160 MVA has been remotely energized using this technology at a 220 kV voltage level.
• The new 160 MVA capacity power transformer installed at a cost of about Rs 6.50 crore at 220 KV sub-station at Jabalpur Nayagaon has been energized using this technology.
• With the electrification of this transformer, the transmission capacity of the Mahakaushalion has increased significantly. Madhya Pradesh Power Transmission Company transmits power from its 58 sub-stations in 8 districts of Mahakaushal region, including two sub-stations of 400 kV and 47 substations of 132KV.
• These include 400 kV side 830 MVA. 220 kV side 3660 MVA and 132 kV side 4607 MVA thus having a total transformation capacity of 9097 MVA.
• Narsinghpur, Damoh, Seoni, Mandla, Dindori and Katni districts of Mahakaushal region will now get additional power of about 50 MW from Jabalpur if needed. It is noteworthy that in this sub-station of Jabalpur, apart from Amarkantak, Birsinghpur, Bargi power generation stations, electricity is transmitted from the power grid.
• Human machine interface technology involves controlling devices remotely using human and computer machines. This technology is used with the help of ADMS in the 3 SCADA Control Center operating in the state of MP Transco.
• It is known that MP Transco has made many innovations in its system in the past as well. These include the implementation of a cyber security system in the first state load dispatch system in the country, implementation of SCADA system, drone patrolling of transmission lines, plan to remotely operate 400 KV sub-stations.
